The project was opposed by many environmentalists who contended that the tunnels would do significant damage to one of the most pristine parts of the state. And it played into the geographic water tensions that have roiled this state for generations, dramatic enough to be the subject of a movie.

There is a certain historic symmetry to this. When he was governor, Pat Brown, Mr. Brown’s father, championed the California State Water Project, which created much of this water network. It was central to California’s expansion, and to Pat Brown’s legacy. The vote may have helped not only to protect his water legacy, but to establish one for his son as well.

Mark Zuckerberg’s visit to Capitol Hill was highly anticipated in both Silicon Valley and Washington, and the internet was along for the ride Tuesday.

There was plenty of jeering and cheering throughout the day, some inside the room and a lot more online. In one particular exchange that caught people’s attention, Senator Orrin Hatch of Utah asked Mr. Zuckerberg if it was his intention to keep Facebook free. Mr. Zuckerberg responded affirmatively.

“Well, if so, how do you sustain a business model in which users don’t pay for your service?” Mr. Hatch asked. A slight pause followed.

“Senator, we run ads,” responded Mr. Zuckerberg, his mouth suddenly curling into a big smile. Others in the room laughed. The internet dug in.

Mr. Hatch’s staff, tweeting later from his official account, posted a longer video of the exchange and prodded some reporters online to look at the whole comments in context. His question, his staff members suggested, were sarcastic and part of a larger point.

“To my mind, the real issue here is transparency, it’s consumer choice. Do users understand what they’re agreeing to when they access a website or agree to terms of service?” he said. (That video received less circulation.)

Senator Richard Durbin of Illinois asked Mr. Zuckerberg if he would be comfortable sharing the hotel where he was staying in Washington.

“No. I would probably not choose to do that publicly here,” Mr. Zuckerberg said.

“I think that may be what this is all about,” Mr. Durbin said. “Your right to privacy. The limits of your right to privacy.”

Senator John Cornyn of Texas asked about Facebook’s former motto: “Move fast and break things.” Mr. Zuckerberg noted it had been changed.

“I don’t know when we changed it,” he replied, “but the mantra is currently ‘move fast with stable infrastructure,’ which is a much less sexy mantra.”
